TDA1085C
PHASE CONTROL INTEGRATED CIRCUIT
MAY 1992
BLOCK DIAGRAM
The TDA1085C is a silicon integrated circuit designed
for use in phase control systems of AC mains with resistive
and inductive loads The circuit may form the basis of
closed loop control systems utilizing tacho frequency or
analog voltage feedback.
The circuit was primarily designed for motor speed
control in automatic washing machines and hence includes
a programmable multiple ramp generator to control
acceleration rates.
FEATURES
I Powered direct from AC mains or DC line.
I Flexible ramp generator to provide controlled
acceleration and distribution period.
I Actual speed derived from tachogenerator
frequency or magnitude.
I Control amplifier allowing loop gain control.
I Symmetrical positive and negative wave firing of
the triac.
I Motor current limiting.
I Fail safe in case of open circuit tachogenerator.
I Repeated triac pulses provided if triac unlatches.
